Title: Die punching circular saw blades from continuous strip - employs several die stations which perform complementary punch operations
Inventor: KELSEY ROBERT DEREK
IPC: B23D65/02
Filed: 1978-10-07
Abstract: In the mfr. of circular saw blades a strip of material which has the thickness and physical properties required in the saw blade is led through a die punching press with several punch stations.

Title: Diesel engine control system - has spring loaded slide locking setting member into stopping position with solenoid off
Inventor: KNORRECK PETER ING GRAD
IPC: F02M63/02
Filed: 1978-11-07
Abstract: The control mechanism is for a diesel engine, having a solenoid valve determining the zero-delivery setting of the injection pump rack. When switched off, this shuts off the connection between a hydraulic chamber pressurised by the fuel lift pump and an unpressurised chamber, fuel bering pref. used as the hydraulic fluid. Pressure in the first chamber slides a setting member against spring action into the stopping position, moving the rack to the zero-delivery position. A locking slide at right angles to the member is moved by a solenoid against spring action, so as to block or free the slide movement. When the solenoids (43) are switched off, the slide (41) is moved by the return spring (44) into an end position locking the member (17) in the stopping position, and into the other end position releasing it when they are switched on.
